CentOS - Oct 2009 - Resolv.conf with multiple adaptors on multiple networks

Hi All,

I did a clean install of CentOS 5.3 yesterday. During setup I  
activated both adapters on startup. etho is my public IP and eth1 is  
my private/internal IP.

It did not let me specify nameservers though.

So I know this is resolv.conf.

I know I put in:
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx

But how do I put in nameservers for specific networks? Example, I want  
my public IP to resolve to the comcast name-servers top get out to  
things like Google. I want internal to default to my internal DNS once  
I have it setup.

Just have everything query your internal DNS.  It can respond directly
for your local domains and then either query the root nameservers or the
Comcast nameservers for everything else.

i second what the others have said, but you can specify nameservers
for each nic in their
/etc/sysconfig/network-scripts/ifcfg-ethX file.
